Description
Die vorliegende Erfindung bezieht sich auf eine Haltevorrichtung zur Befestigung eines Gebläses an einem wärmeabführenden Kühlkörper.The present invention relates on a holding device for attaching a blower to a heat dissipating Heatsink.
Viele Halbleiterelemente geräte erzeugen während des Betriebs Wärme, die abgeführt werden muss, um eine Beschädigung des Elements zu verhindern. Manche dieser Elemente haben eine beschränkte Belastbarkeit, die größtenteils durch ihre Fähigkeit, intern erzeugte Wärme abzugeben und dadurch allgemeine oder örtliche wärmebedingte Zerstörung oder Ausfälle in ihnen zu vermeiden, bestimmt wird.Many semiconductor devices produce devices during the Operating heat, the dissipated must be to damage to prevent the element. Some of these elements have limited resilience, for the most part through their ability internally generated heat to deliver and thereby general or local heat-related destruction or losses to avoid being determined in them.
Bei manchen Halbleiterelementen reicht die Abführung der intern erzeugten Wärme über das Gehäuse, den Kopf oder die Zuleitungen des Geräts aus. Bei vielen Halbleiterelementen ist es jedoch notwendig, das Abführen der intern erzeugten Wärme durch den Einsatz von Kühlkörpern zu unterstützen. Zum Abführen von intern erzeugter Wärme aus gepackten elektronischen Elementen, die Halbleiterelemente enthalten, wird eine große Vielfalt von Kühlkörperkonstruktionen eingesetzt. Zum Zwecke der vorliegenden Erfindung ist ein Kühlkörper ein Körper aus Metall oder ähnlichem Material, welcher mit einem elektronischen Element in Kontakt gebracht wird, um intern erzeugte Wärme aus dem gepackten elektronischen Element enthaltenen Halbleiterelementen weiterzuleiten und die intern erzeugte Wärme durch Übertragung, Konvektion und/oder Strahlung schnell an die Atmosphäre abzuführen.With some semiconductor elements it is enough the exhaustion of the internally generated heat through the Casing, the head or the leads of the device. With many semiconductor elements however, it is necessary to remove of the heat generated internally the use of heat sinks support. To the lead away of internally generated heat from packed electronic elements containing semiconductor elements, will be a big one Variety of heat sink designs used. For the purposes of the present invention, a heat sink is a Body out Metal or the like Material that is brought into contact with an electronic element, about internally generated heat semiconductor elements contained in the packed electronic element forward and the internally generated heat by transmission, convection and / or Radiation quickly to the atmosphere dissipate.
U.S.Patent 4 884 331 (Hinshaw) zeigt einen weitverbreitet eingesetzten Kühlkörper, der allgemein als Nadelrippen-Kühlkörper bezeichnet wird. Der Kühlkörper weist Reihen und Kolonnen von hochstehenden parallelen Rippen auf. Die Kühlkörper werden durch Extrudieren von Reihen hochstehender Rippen und dann Querschneiden der Rippen geformt, so dass Reihen und Kolonnen von nadelförmigen Rippen entstehen.U.S. Patent 4,884,331 (Hinshaw) shows a widely used heat sink, commonly referred to as a needle fin heat sink becomes. The heat sink points Rows and columns of raised parallel ribs. The Heatsink by extruding rows of raised ribs and then cross cutting of the ribs shaped so that rows and columns of acicular ribs arise.
Diese Konstruktionen reichen häufig aus, um eine Selbstkühlung der elektronischen Elementen zu bewirken. Bei manchen Anwendungen ist es jedoch wünschenswert, ein Gebläse hinzuzufügen, welches Kühlluft über die Rippen des Kühlkörpers bläst. Nach dem Stand der Technik wird so vorgegangen, dass zum Befestigen eines Gebläses an einem Kühlkörper eine Schraube oder ein ähnliches Befestigungselement durch die Befestigungslöcher des Gebläses in den Platz zwischen hochstehende nadelförmige Rippen eingeführt wird. Dies ist nicht zufriedenstellend, da häufig ein Platz zwischen den nadelförmigen Rippen nicht mit allen Befestigungslöchern des Gebläses fluchtet. Die Haltevorrichtung der vorliegenden Erfindung beseitigt dieses Problem.These constructions are often sufficient for self-cooling of the electronic elements. In some applications however, it is desirable a blower add, what cooling air over the Ribs of the heat sink are blowing. After this State of the art is used in such a way that for attaching a blower on a heat sink one Screw or something similar Fastening element through the mounting holes of the blower in the Space is inserted between upstanding needle-shaped ribs. This is unsatisfactory as there is often a space between the needle-shaped ribs not with all mounting holes of the blower flees. The holding device of the present invention is eliminated this problem.
WD-A-9639889, welche unter Paragraph 54(3)EPC fällt, offenbart des Weiteren eine Haltevorrichtung zur Befestigung eines Kühlkörpers an einem Gebläse. Diese Haltevorrichtung ist jedoch nicht, wie in Anspruch 1 beansprucht, mit einer Noppe an der Lamelle versehen.WD-A-9639889, which is described in paragraph 54 (3) EPC falls further discloses a holding device for fastening a Heat sink a blower. However, this holding device is not as claimed in claim 1, provided with a knob on the slat.
Ein Ziel der vorliegenden Erfindung besteht darin, eine Haltevorrichtung vorzusehen, die den Anbau des Gebläses an einen Kühlkörper wesentlich erleichtert.An object of the present invention consists in providing a holding device that the cultivation of the blower essential to a heat sink facilitated.
Kurzdarstellung der ErfindungSummary the invention
Gemäß vorliegender Erfindung ist eine Haltevorrichtung vorgesehen, wie sie in Anspruch 1 definiert ist. Die Haltevorrichtung weist Mittel zur Befestigung des Gebläses am Rahmen auf. Der Rahmen wird zwischen die Rippen des Kühlkörpers geklemmt und anschließend vor Ort fixiert. Die rechteckige Form des Rahmens passt zwischen die Reihen und Kolonnen der Rippen am Kühlkörper.According to the present invention a holding device is provided as defined in claim 1 is. The holding device has means for fastening the fan to the frame on. The frame is clamped between the ribs of the heat sink and then in front Fixed location. The rectangular shape of the frame fits between the Rows and columns of ribs on the heat sink.
Der Rahmen wird aus einem Blech aus federndem Metall geformt. Die Lamellen erstrecken sich nach unten aus dem Rahmen heraus. Sie werden zwischen die Kolonnen der nadelförmigen Rippen in den durch Querschneiden gebildeten Platz eingeschoben.The frame is made from a sheet of metal resilient metal shaped. The slats extend downwards out of the frame. You will be between the columns of needle-shaped ribs inserted into the space formed by cross cutting.
Die Haltevorrichtung der vorliegenden Erfindung besitzt bedeutende Vorteile, wenn sie mit der Lamelle zwischen die Kolonnen der durch Querschneiden gebildeten nadelförmigen Rippen eingedrückt wird. Der Querschneidespalt zwischen den Kolonnen der nadelförmigen Rippen ist schmal und weist eine konstante Abmessung auf. Dieser Umstand sorgt dafür, dass die erfindungsgemäße Haltevorrichtung immer sicher in den Kühlkörper eingreift und sicher in diesem fixiert ist. Andererseits variiert der Spalt zwischen den extrudierten Reihen der nadelförmigen Rippen – in Abhängigkeit von der Größe des Kühlkörpers. Eine Haltevorrichtung einer bestimmten Größe lässt sich nicht in den extrudierten Reihen aller Kühlkörper festklemmen.The holding device of the present Invention has significant advantages when compared to the lamella between the columns of the acicular ribs formed by cross cutting pressed becomes. The transverse cutting gap between the columns of the acicular ribs is narrow and has a constant dimension. This condition ensures that the holding device according to the invention always securely engages the heat sink and is securely fixed in this. On the other hand, the gap varies between the extruded rows of acicular ribs - depending on the size of the heat sink. A Holding device of a certain size cannot be used in the extruded rows clamp all heat sinks.
Das Einführen der erfindungsgemäßen Haltevorrichtung in quergeschnittene Spalte zwischen Kolonnen von nadelförmigen Rippen hat einen weiteren wichtigen Vorteil. Die Rippen weisen oft eine größere Stärke in extrudierter Richtung auf, nämlich in der Richtung, gegen die die Fixierkraft der Haltevorrichtung aufgebracht wird.The introduction of the holding device according to the invention in cross-cut gaps between columns of needle-shaped ribs has another important advantage. The ribs often have one greater strength in extruded Direction up, namely in the direction against which the fixing force of the holding device is applied.
Die erfindungsgemäße Haltevorrichtung lässt sich an ver-schiedene Kühlkörpergrößen und an verschiedene Gebläsetypen anpassen. Die erfindungsgemäße Haltevorrichtung kann in Kühlkörper eingeführt werden, die relativ lange oder relativ kurze nadelförmige Rippen aufweisen. Bei den Kühlkörpern mit längeren nadelförmigen Rippen geht die Haltevorrichtung nicht bis auf den Grund, sie ist jedoch sicher vor Ort fixiert.The holding device according to the invention can be to different heat sink sizes and to different blower types to adjust. The holding device according to the invention can be inserted into heat sink which have relatively long or relatively short acicular ribs. at the heat sinks with longer acicular Ribs the holding device does not go to the bottom, it is but securely fixed on site.
Die Haltevorrichtung kann zur Befestigung von Gebläsen verschiedener Typen verwendet werden. Hierzu gehören Gebläse, die an den Ecken mit Schlitzen oder Löchern versehen sind.The holding device can be used to attach blowers different types can be used. This includes blowers that have slots at the corners or holes are provided.
Erfindungsgemäß sind die Lamellen des Rahmens mit bogenförmigen Ausnehmungen versehen. Die bogenförmige Ausnehmung hält einen Z-förmigen Halter im Kühlkörper fest. Dies erleichtert den Anbau eines Kühlkörpers mit einem Sockel, wobei der Z-förmige Halter zum Befestigen des Kühlkörpers an einem elektronischen Element dient.According to the slats of the frame with arcuate recesses are verses hen. The arcuate recess holds a Z-shaped holder in the heat sink. This facilitates the mounting of a heat sink with a base, the Z-shaped holder being used to fasten the heat sink to an electronic element.
Ferner weisen erfindungsgemäß die extrudierten Rippen des Kühlkörpers einen Grat oder eine Kerbe auf, um den Rahmen am Kühlkörper festzuhalten. Dies verhindert das Herausziehen der Gebläse-Baugruppe aus dem Kühlkörper. Der Grat oder die Kerbe wird während des Extrudierens geformt, bevor durch Querschneiden der Kühlkörper mit nadelförmigen Rippen gebildet wird, die Erfindung kann jedoch auch an einem extrudierten Kühlkörper eingesetzt werden.Furthermore, according to the invention, the extruded Ribs the heat sink one Burr or a notch to hold the frame to the heat sink. This prevents pulling out the blower assembly from the heat sink. The Ridge or the notch will be during of extrusion molded before using the heat sink by cross cutting acicular Ribs is formed, but the invention can also be extruded Heatsinks are used.
Gemäß einer weiteren Modifikation der Erfindung sind die Rippen des Kühlkörpers gezackt, so dass eine Reihe von Kerben und Graten entstehen. Die Haltevorrichtung des Gebläses wird bis auf eine gewünschte angemessene Tiefe eingedrückt. Auf dieser Tiefe passt die Haltevorrichtung in die Kerbe. Anstatt in einer bestimmten Kerbe oder an einem bestimmten Grat fixiert zu werden, ergibt sich somit eine gewisse Flexibilität beim Positionieren der Haltevorrichtung am Kühlkörper.According to another modification the ribs of the heat sink are serrated, so that a A series of notches and ridges arise. The holding device of the blower is down to a desired one reasonable depth indented. The holding device fits into the notch at this depth. Instead of fixed in a certain notch or on a certain ridge So there is a certain flexibility in positioning the holding device on the heat sink.
Des Weiteren verhindert erfindungsgemäß eine Noppe an der Haltevorrichtung, dass diese und das Gebläse seitwärts im Kühlkörper verrutschen. Die Noppe passt zwischen zwei Nadeln in einem Kühlkörper mit nadelförmigen Rippen, um eine Seitwärtsbewegung zu vermeiden.Furthermore, according to the invention, a pimple prevents on the holding device so that it and the fan slide sideways in the heat sink. The pimple fits between two needles in a heat sink with needle-shaped ribs, a sideways movement to avoid.
